Optimal value

This is the highest or lowest value the graph reaches

*Also known as the minimum/maximum value

Factored form {y= a(x-s)(x-r)}

To find the optimal value you sub the A.O.S into the equation and solve for it

Vertex form {y= a(x-h)² + k}

The optimal value is k in the expression y= a(x-h)² + k

Standard Form {y= ax² + bx + c}

To find the optimal value you sub in the A.O.S into the equation
